Dedicated Instance Class

<p><strong>1.&nbsp; </strong><strong>What is the difference between the Dedicated Instance on a Dedicated Host and ECS?</strong></p> <p>The functions of the Dedicated Instance and ECS are basically the same, but the compute performance and stability of the former are better. The physical resources of the Dedicated Host are in the exclusive use of the tenant. The Dedicated Instance on a Dedicated Host runs in a single-tenant environment.

ECS provides multiple tenants with shared physical resources.</p> <p>&nbsp;</p> <p><strong>2.&nbsp; </strong><strong>Can I create Dedicated Instances with different specifications on the same Dedicated Host?</strong></p> <p>Yes. You can create Dedicated Instances with different specifications on a Dedicated Host to meet your business requirements.</p> <p>&nbsp;</p> <p><strong>3.&nbsp; </strong><strong>Can I adjust the specification of a Dedicated Instance?</strong></p> <p>You can adjust the specification of a Dedicated Instance within the available capacity of the Dedicated Host.</p> <p>&nbsp;</p> <p><strong>4.&nbsp; </strong><strong>If the capacity of the Dedicated Host&rsquo;s local disk is not enough, can I create an EBS volume?</strong></p> <p>This feature is not supported currently.</p> <p>&nbsp;</p> <p><strong>5.&nbsp; </strong><strong>Can an ECS instance be migrated to a Dedicated Host?</strong></p> <p>The feature is not currently supported but in planning.</p>
